No. 62%,119, nowlPatent No. 2,982,819, dated his 2, 61. Divided and this applicationMar. 1, Il il, Ser. No. 2,5il3 l8 tillaims. (Cl. 173-33) This inventionrelates to printing telegraph receiving and selecting mechanism and hasparticular reference to reception mechanisms for such telegraphicsystems wherein is employed the well-known five unit Baudot code. Thisapplication is a division from co-pending application Serial No.628,110, filed December 13, 1956, now Patent No. 2,982,810, issued May2, 1961.

With the increasing use of interofrice telegraphy and integrated dataprocessing systems, it is advantageous to transmit the units of a codegroup in simultaneous form over a plurality of wires. By usingsimultaneous transmission, less complex and higher speed translators canbe used at the various receiving machines. Along with the use ofsimultaneous transmission systems, reierred to above, it may be desiredand is often necessary to transrnit the same code in conventionalsequential form to other apparatus in the system or to a telegraph linefor distant communication, and it therefore follows that mechanism mustbe provided to receive the code combinations in either or both forms,simultaneous and sequential.

The structure disclosed in parent application Serial No. 628,110, new U.S. Patent No. 2,982,810, issued May 2, 1961, includes keyboardtransmitting equipment that can transmit the units of a code insequential arrangement and simultaneous arrangement. Both forms oftransmission can be sent at the same time or either form can be sentindependently to the exclusion of the other by appropriate positioningof a switching control system. The invention of the present applicationincludes a translating mechanism capable of receiving and translatingeither form of signals, sequential or simultaneous, which can betransmitted by the keyboard transmitter disclosed in the parentapplication or by two separate transmitters and is incorporated in arepcrforator structure.

Accordingly, a primary object of this invention resides in the provisionof a novel receiving mechanism adapted to the reception of eithersimultaneous or sequential forms of the Baudot or similar codes.

Still another object resides in providing a novel combination printer toreceive either sequential or simultaneous code units. As a corollary tothis object the novel printer can be embodi d in a printingreperforator.

Another object resides in the provision of novel receiving mechanismwhich can translate incoming sequential code signals to simultaneouselectrical conditions for simultaneous translation to mechanicaloperation such as printing or perforating or both.

Still other objects reside in the provision of new components inreceiving structure enabling sequential code signals to be translated tosimultaneous electrical conditions, thence by further translation tomechanical operating conditions, and these components include a novelsliding contact structure with a printed circuit board. Also included inthese objects are contact structure locking mechanism and a control inthe sequential receiving structure to start actuation of thesimultaneous signal translating equipment.

Still another object resides in providing a novel receiving structurefor receiving sequential or simultaneous code signals to be translatedto a mechanical operation wherein when sequential signals are received,both sequential receiving mechanism and simultaneous receiving mechanismare operative to translate to a mechanical operation and whensimultaneous signals are received, the sequential mechanism is notoperative.

A still further object resides in providing a novel mechanism forreceiving simultaneous incoming code signals and translating theelectrical conditions to mechanical positions including a unitarysolenoid structure with twoposition plungers adapted to besimultaneously actuated to position mechanical selecting mechanism. Infurtherance of this object the mechanical selecting mechanism includes agroup of Y-levers independently positioned by the plungers, a transfermechanism with a function shaft and a positive clutch with a solenoidcontrol. The solenoid control is pulsed to permit engagement of thepositive clutch immediately after the simultaneous signals are receivedto thereby transfer the mechanical position of the Y-levers and permitthe next group of simultaneous signals to be received by the unitarysolenoid structure.

GENERAL DESCRIPTION The equipment embodied in this receiving inventionwill be described generally in connection with a telegraph keyboardbasically similar to that disclosed in E. E. Kleinschrnidt et a1. PatentNo. 2,773,931 for Printing Telegraph Apparatus, with a keyboard operatedsequential code unit transmitter substantially similar to that disclosedin the E. F. Kleinschrnidt et al. US. Patent No. 2,754,364. As disclosedin the aforementioned patents, pressing of a key moves five permutationbars to left and right hand positions indicative of space (no-current)and mark (current) conditions of the code. A sixth bar is invariablymoved to the right by the pressing of a key and is instrumental inreleasing a transmitter camshaft to make onehalf revolution. As thecamshaft revolves, six cam lobes are presented in sequential order tosix cam followers and the cam followers are conditioned by thepermutated positions of the code bars to allow one or the other of theirends to be raised by the passage of the associated cam lobs. Thisselective raising of one or the other ends of a follower causes anelectrical contact to be closed or opened to provide a sequence of timedcurrent or no-current electrical conditions to be transmitted over asingle wire line. Seven of these pulses make up a code signal for eachof thirty-two different combinations; the first pulse is always one ofno-current, the succeeding five pulses are permutatively selective andthe seventh pulse is invariably a current pulse. After the camshaft hasmade one half revolution, in which time the seven pulses aretransmitted, it is stopped and will be ready for the next key to bedepressed for transmission of the next code signal. The speed of thetransmitter camshaft is synchronized with the receptive speed of theassociated telegraph equipment and is normally in the order of sixtywords per minute. Using a transmitter, as briefly described above,sequential signals maybe sent out on the line and the message may bemonitored on a local page printing machine such as the one disclosed inthe above mentioned Patent No. 2,773,931.

For more economical use of line time and for smoother operation of thereceiving equipment, it is advantageous to store the messages producedby the keyboard for future transmission. Message storage can beaccomplished in various ways, e.g., holes punched in a paper strip ormagnetic spots on -a steel tape. In the present invention, storage ofmessages is performed by a perforator which prints a type character andpunches code holes in the tape. The perforator has two coordinatedreceiving mechanisms, one of which is adapted to receive incomingsequential signals from a line and the other of which is adapted toreceive simultaneous signals directly from a keyboard. The new keyboardtransmitter disclosed and claimed in the aforementioned parentapplication includes basic keyboard structure of the aforementioned US.Patent No. 2,754,- 364, but the left side of the keyboard transmitterincludes a simultaneous switch mechanism which is controlled by themovement of the code bars (see FIGURE 9). Each code bar will move aswitch member to the left or right according to the code condition, thensimultaneously completing'a group of permutated mark or spaceconnections to a solenoid structure at the perforator, which is adaptedto these simultaneous circuits, will operate to translate the code tomechanical conditions and record it on the tape.

When the equipment is used for only simultaneous transmission andreception, the perforator'may be operated at a speed greater than thenormal typing speed so the typist may manipulate the keyboard in thesame free manner as used in operating an electric typewriter. Thisfeature constitutes quite an advantage particularly when the message isbeing stored for future transmission on 1 single line and especially foroperators who are not used to the restricted speed of a conventionaltelegraph keyboard. a

The coded tape, which contains the stored message, may be subsequentlyfed to a tape transmitter, a suitable transmitter being disclosed in theE. F. Kleinschmidt US. Patent No. 2,923,769, wherein the coded tape isread and sequential signals placed on the transmission line. .Theseoutgoing signals may be monitored by the local perforator-through itssequential receiver or they may be monitored by a local page printer, inwhich case the per-' forator will be free to record incoming messages orto store. furtherv messages from thelocal keyboard.

' The sequential receiver of the perforator includes the conventionalsingle'rela'y receiver with selecting levers,

4 In this invention, the sequential receiver cooperates with associatedmechanismto translate the incoming sequential pulses into simultaneousswitch positions which in turn operate the simultaneous receiver of theperforator which hasbeen briefly referred to. The receiver mechanismwill now be described.

RECEIVING MECHANISM (REPERFORATOR) The receiver of this particularembodiment (depicted in skeletonized perspective in FIGURE 5) is knownin the art as a reperforator. It will receive a telegraph message from awire and translate the electrical code signals into mechanicaloperations to type the message on a paper tape and at the same timerecord the code in the tape by means of punched holes. A reperforator ofthe nature referred to is disclosed in United States application SerialNo. 472,076, filed November 30, 1954, now US. Patent No. 3,014,095, towhich reference may be made for details of typewheel, printing andperforating mechanism not illustrated herein. In order to mechanicallyutilize the electri cal form of the received code signals, the elementsof the code must be converted into mechanical settings. U.S.'

' Patent No. 2,754,361 discloses a selector for this purpose,

components of which are employed as subcomponents in' the specificreceiver embodiment of this invention. A very brief description of thesequential selector of this device and its operation will now be given.

7 All of the receiving selector mechanism, both sequential andsimultaneous, is located at one side of the reperforator and theessential elements are shown in FIG- URES 1 and 5. To receive sequentialsignals to be converted to mechanical settings, there is a selectormagnet 244 with a movable armature 246. The winding of selector magnet244 receives the sequential electrical pulses of the code combinationand armature 245 is caused to move to one of two positions, depending onwhether the V of the five electrical impulses that comprise any codecombination group is recorded in the form of clockwise orcounterclockwise movement of five corresponding Y- levers 248. This isaccomplished through the use of five selector cam lobes 25% operating inconjunction with five selector levers 252 and the armature 246. The fiveY- levers 248 are mounted on a common pivot stud 254-, the five selectorlevers 252 are mounted on a pivot stud 256 and the five selector camlobes 250' are mounted in axially spaced relation on a rotatablecamshaft 258 with the cam lobes projecting at progressively offsetanglesfrom the camshaft 258. One selector cam lobe 25t3operates inconjunction withonly one associated selector lever 252 and that leverwith only one associated Y-lever 243. Thus there are five planes, one inback of the other, each con taining a set of these three parts. The end268 of the selector magnet armature 246 is broad enough to engage allfive selector levers. Each of these five sets of parts records one ofthe impulses of the five unit code. The

first set records the first impulse, the second set the sec ond impulse,etc. a

, "During the time a marking impulse is received, the selector magnetarmature blade 2'50 ismoved into the path of aselector lever 252. Nearthe middle of this time pe- .riod,'the selector cam lobe 25f)corresponding to the impulse being received will be rotating, willengage and raise the selector lever 252. As the armature blade 26%,

being positioned in the path of a selector lever 252, prevents raisingof the right end of the selector lever, the selector lever is forced. torise at its left endby' sliding on the bearing shoe 262. In so doing,the selector lever 252 pushes against the Y-lever 248 at its end 264,turning the Y-lever clockwise (unless it is already in that position).Further rotation of'the selector camshaft 253 per mits the selectorlever 252m drop back, but the Y-lever 248- is held in the clockwiseposition by a detent 266-. A marking impulse is' thus recorded in theform of the clockwise position of a Y-lever. V

During the time a spacing impulse is received, the selector magnetarmature blade 26%) is moved away from the selector levers 252. Near themiddle of this time period, the rotating selector cam lobe correspondingto the impulse being received will engage and raise the correspondingselector lever 252. The end 25% of the armature does not obstruct theright-hand end of the selector lever 252, therefore the right-hand endis free to rise. In rising, the right-hand end of the selector lever 252pushes up against the end 268 of the Y-lever 243, turning the Y-levercounterclockwise (unless it is already in that position). A spacingimpulse is thus recorded in the form of the counterclockwise position ofa Y-lever. The Y-lever detent 266 also holds the Y-lever in the spaceposition.

To synchronize the selector cam lobes 250 with the incoming electricalimpulses, cam lobes 25% are set into motion from a stopped position atthe start of each code group and stopped at the end of each code group.The selector camshaft 250 is driven by a drive shaft 27%) through afriction clutch 2.72. Normally when no mes sages are being received,current flows in the windings of the selector magnet 24 i and thecamshaft 258 is prevented from turning by the interoperation of theselector magnet armature blade end 266, stop lever 274, and a camsi aftstop plate 276. When moved to the left, the armature blade end 26%?engages the stop lever 274 which in turn prevents the stop plate 276 andselector camshaft 253 from turning. When the start (no-current) impulsefor a code group is received, the armature end 25% is moved to disengagethe stop lever 27 i, releasing it and the stop plate 276; the selectorcamshaft 258 immediately starts to rotate, bringing the first selectorcam lobe 25:; into engagement with its selector lever 252 by the timethe next impulse of the code group (first bit) is received.

Thereafter, each of the remaining five selector cam lobes strilies itsrespective selector lever when the cor-respending code bit is beingreceived. All five cam lobes operate their selector levers within onehalf revolution of the camshaft. The camshaft is limited to making onlyone half revolution per code group because, after the last five bitimpulses are received, the stop impulse moves the magnet armature 246 tothe left to engage the stop lever 274. The other end of the stop plate276, which then comes around, engages and is held by the stop lever 274to stop the camshaft 258. If further details of the sequential receivingstructure is desired, reference is made to US. Fatent No. 2,754,361.

TRANSFER FRGM SEQUENTIAL TO SHVIULTANEOUS Referring to FIGURES l, 2 and5, the receiver mechanism has five dielectric code plates 23% of a codeactuated switch which must be positioned according to the incomingsequential code group in order to convert the sequential form of thecode group to a simultaneous form to be received by five solenoids forsubsequent conversion to printed and punched tape. The incoming codegroup as stored in the Y-levers 2-48, by clockwise and counterclockwisesettings, is transferred to the dielectric code plates 2% by mechanismto be now described.

Each code plate 28 3, at its lower end, carries a slotted metallic shoe232 which mates with a corresponding tail 284 of one of five T-levers286, all of which are mounted on a common pivot 238 carried on the endof a transfer lever 29%. The five code plates 28% are mounted forreciprocation on two fixed posts 283 and 235 which pass throughappropriate slots in the code plates. Turning a T-lever 285 on its pivotwill cause its mating code plate ass to move up or down. The T-leversare mounted in the same planes as their corresponding Y-levers, andmovement of the transfer lever 2% engages certain ones of the ends ofthe T-levers 236 with certain ones of the ends of the Y-levers 243. Theends 292 and 294 of the arms of T-levers 286 are spaced farther apartthan associated ends 2% and 293 of Y-levers 243. Therefore,

only one end of the T-levcr can engage one end of a Y lever at any timeand the ends which engage will depend upon Y-lever position. When thetransfer operation takes place, the transfer lever 29% moves all of theT-levers against the Y-levers and the T-levers assume positionscorresponding to associated Y-levers, thus transferring the five storedcode settings of the Y-levers to the T-levers and thence to the codeplates 28% The transfer operation, a reciprocatory swinging movement ofthe transfer lever 2%, takes place after the fifth code bit is stored inthe Y-levers but before the selector camshaft 258 is brought to rest bythe stop signal. A sixth or transfer lever latch tripping cam Still,FIGURE 5, mounted on the selector camshaft 258, trips a transfer levertrip latch 3% which holds transfer lever 2% in a left-hand position, andthe transfer lever 2% is pulled clockwise by the transfer lever spring334. The timing of the latch tripping cam 369, with respect to the fiveselector cams 25% and stop plate 274, is such that the tripping actiontakes place only after the Y-lever selecting operation is completed andbefore the selector camshaft 258 is stopped.

Each of the live code plates 2% is associated with one of five contactwipers 3%, each of which is disposed in a cut-out 3th in the upper endof one code plate. With reference to FIGURES 2 and 3 for details, thesecontact wipers 3&8 are square in cross section and are bent in the shapeof a W with the two ends 312 and 314 forming the wipers and the middleU-section 316 forming an anchor clip for a biasing spring 313. Eachwiper 3% (FIGURE 2) slides within slot 32% of a guide block 322, oneslot being provided for each wiper. Guide block 322 is fas toned to aswitch plate 324 by screws 326. The width of block 322 (FTGURE 2) isnarrower than the cut-outs 31% in the ends of code plates 2% to permitunobstructed movement of the code plates when they slide into mark andspace positions. Biasing springs 318, one for each wiper 3'33, passthrough an opening 323 in switch plate 324, through a hole 33% in abacking block 332 and are attached to an anchor bar 334 located at therear of the hole 3%.

The printed circuit switch plate 324, FIGURE 4, has two contact stripsand 33%, disposed adjacent opposite side edges of opening 328, whichprovide the common contacts of the simultaneous circuit. These commoncontact strips 335 and 338 are connected and terminate at a pin The aim312 of the wiper 368 is associated with the common strip 336 and the arm314 is associated with the common strip 333 and one or the other of thewiper arms 312., 314 always rests on one or the other of the commonstrips when the wiper 393 is in spacing or marking position. The printedswitch plate 324 also provides two more contacts for each contact wiper,one (342) above the strips 330 and one (34 4) below the strip 338. Eachof these contacts 34p and 3 has printed circuits which terminate at pinsEdda, b, c, z! and e, and 343a, b, c, a and 2. Thus, when a code plateis in the upper position (spacing), the lower arm 314 of the wiper 3338rides against the lower common contact strip 333 while the upper arm31?. rides against its associated contact 342., closing one circuit tothe simultaneous selecting mechanism. In this manner, each code plate 2%closes one circuit if the impulse it represents is a marking impulse, orcloses a different circuit if the impulse it repre seats is a spacingimpulse.

A code actuated switch function shaft 35%, FiGURE-S 1 and 5, performsthree main functions: (1) it restores the transfer lever 29d andassociated mechanism to its latched position; (2) it provides power toregister and lock the code plates 28% in place, and (3) it controls aswitch which energizes the circuits of the simultaneous receivingmechanism, to be later described.

Function shaft 35% is driven in a counterclockwise direction through atoothed clutch 352 at the right-hand end of the shaft. Shown in FlGURE5, a spur gear 354, carryto rotate.

, transfer lever 2% toward the restored position.

ing one part of clutch 352, is in constant rotation through itsengagement with a driving gear 356 on the power shaft 270. The clutch352 is engaged when the transfer operation takes place and isaccomplished by the clockwise turning of clutch latch 358 which, througha shaft 360, is connected to the transfer lever 290 and is rotated whenthe transfer lever latch 392 is actuated to release the transfer lever.Turning of clutch latch 358 permits the clutch members to springtogether and function shaft 35%) starts The T-levers 286 must be movedaway from the Y-levers before the next code group can be set up in theY-levers and this action is accomplished when the transfer lever 290 isrestored to the latched position. The transfer lever 290 must be rotatedslightly counterclockwise against the tension of the spring 304 andlatched in this position by the transfer lever latch 3&2. A cam 362 atthe left-hand end of the function shaft 350 operating on a roller364,1nounted on an extension arm of transfer lever 290, accomplishesthis restoring action during a one-half revolution of the shaft 350' by'camrning the Near the end of the one-half revolution, as the transferlever moves into restored position, the transfer lever latch spring 366pulls the transfer lever latch 332 into position to latch the transferlever. l p

. After the five code bits have been received by the sequentialreceiver, and the associated selector mechanism has caused thepositioning of the five code plates 280, the

plates 280 are registered and locked in place to align the contactwipers 368 in their exact correct selected positions. As illustrated inFIGURE 5, this function is performed by the interoperation of a cam 368on the function shaft 350, a cam follower 370 on an extension of aregistering lever 372, pivoted at 374, and having a registering bail 376on a second extension. Registering lever 372 is biased clockwise by aspring 377. While the selection and transfer operations are takingplace, the cam follower 370 rests on the high portion of the cam 368.The function shaft 350 is stationary during this time so the cam 368 isnot rotating. When function shaft 35% is coupled to the drive gear 354through clutch 352 so shaft 350 starts to rotate, the cam follower 37f)drops off the high portion of the cam 368 and the bail 376 moves upagainst notches 378 of'the plates 280. The notches 378 are aligned withthe upper notches of the mark positioned code plates in line with thelower notches of the, space positioned code plates, so that the fivenotches are simultaneously engaged by the bail 376 of the lever 372. Thenotches 378 are V-shaped and the bail 376 has a knife edge, henceslightly out-of-line code plates are cammed into place as the registerbail 376 engages the notches.

To prevent arcing at the contacts of switch plate 324 when wipers 308slide into their selected positions, the electric circuit to the commoninput ofplate 324, which is received at the pin 340, is held in opencondition. After the bail 376 positions and locks the plates 280, thesimultaneous. circuit is pulsed. A cam 380 (see FIGURES on the functionshaft 350 is associated witha pair of contacts 382 in series with theenergizing circuit to the simu1- taneous receiving mechanism, and whenthe lobe of cam .380 strikes the contacts 382 they will be closed topulse the simultaneous code plate circuit.

SIMULTANEOUS RECEIVER Five solenoids arranged in a unitary assembly areemployed to operate the simultaneous receiving mechanism of thisinvention and by this arrangement a set of five Y-levers are positionedsimultaneously instead of sequentially as in the above describedsequential receiver. The

operating subcornponent of the present receiver mech-.

-anisrn, it will be herein described in detail.

specific reference to FIGURE 6, an iron housing 386 contains thesolenoids. Housing 336 is an assembly of two blocks, an upper block 388and a lower block 3%, fastened together by screws 392 through flanges394 on the two blocks. Each of the blocks 338 and 390 has five verticalchambers 396a, b, c, d and e, in the upper block, and 398a, b, c, d ande in the lower block, to receive solenoid coils 436 (upper) and 4%(lower). The corresponding upper and lowerchambers 3% and 398 arealigned and arrayed in the manner illustrated in FIG- URE 7 wherein thevertical axes of the chambers 396, 3% are spaced apart, from front toback, a distance equal to the spacing of a group of setting elements 452(Y-levers) which are disposed directly below the solenoid housing 386.The spacing of the axes of the chambers 3%, 3 98 in the other directionplaces two of them, the axes of' chambers 33612 and 396d, on the rightof the center line of the housing 388 and three of them, the axes ofchambers 396a, 3%;- and 3962, on' the left of the center line. Upper andlower chambers 3% and 398 are bored from the abutting ends of the blocks388 and 3% and terminate a short distanoe'from the outside ends of theblocks. Smaller coaxial threaded holes 4% and 462 (FIGURE 6)'connect theends of the respective ghambers 396 and 393 to the outside ends of thehousing Sandwiched and clamped between the two blocks 383 and 390 is aniron or mild steel plate 464 with holes drilled in it to align with theassociated chambers 396, 398 of the housing 386. These holes areslightly smaller in diameter than the chambers 3%, 38,.providing aslight shoulder at the inner end 'of each chamber portion 396 and 398,for a reason which will presently become apparent.

The assembled receiver solenoid unit contains the following elementswithin each chamber as illustrated by the cross-sectional view of theone chamber seen in FIGURE 6. The two solenoid coils 466 and 463, woundon sleeve cores 439, made of insulating material, are

heldsnugly between the ends of the respective upper and lower portions396 and 3930f each solenoid chamber and the aforementioned shoulder,provided by the midplate 404, by spring washers 4H and 4-12. Passingthrough the sleeve cores 469 of the coils 406 and 408 and through theassociated hole in the mid-plate 464 is a non-ferrous metallic sleeve414 within which an iron or mild steel. plunger 416 is disposed with-afreely slid able fit. Each plunger 416 has conical ends 418 and 419 andits lower end 4-19 has an axial bore within which the end of a wire 420is press fitted. Plungers 416 are free to independently move up anddo-wnwithin the plugs 422 and 424. Plugs 422 and 424 are identical except fora here through the axis of each of the lower plugs 424 through which theaforementioned wires 420 project. Each of plugs .4 22 and 424 have athreaded portion 426 to mate with the threaded holes 436 and 462 at theend of the upper and lower cylinders, and a smaller inner cylindricalend 423. The inner ends 423 of upper plugs 4-22 have conicalrecesses'43ii to' mate wlth the conical plunger tips 418 and the ends428 oi lower plugs 424, a frusto-conical recess 431 to mate with thelower tips-4 19 of plungers 416. Each plug 422-and 424 has an outerhexagonal head 432 for tool I engagement, and each has alocknut'434'threaded on its threaded portion 426. Plugs 422 and 424areturned into the holes 460 and 402 a distance which will allow betweeninch to inch longitudinal movement of the associated plungers 416 withincylinders 414. The reason 7 for variations in plunger movement will belater described. .When the proper amount of movement of each plunger.

has been set, the lock nuts 434 are turned down against the housing 336to securethe plugs. V Centrally locatedjin upper block 38 i3 is alongitudinal through bore 435 aligned with a centrally located hole (notshown) in the plate ill-t. Channels 14% and 442 (FIGURE 6) in the insidefaces of the blocks 388 and 3% (also shown dotted in FIGURE 7) connecteach solenoid chamber with the central bore In the assembled solenoidblock these channels provide passages to enable the wires from the tensolenoid coils 4% and 408 to be led through the central bore 436 tooutside connections.

Magnetic detent of the solenoid plungers will be described withreference to a schematic magnetic circuit of the above describedsolenoid group shown in FIGURE 8. The plunger .16 is illustrated in itslower position which is the space position for this particular solenoid.The lower convex conical tip 419 of the plunger is held against theconcave conical end 431 of the lower plug 424 due to magnetization ofthe steel plug 424. The polarization of this magnetized plug 42 asshown, is with the South pole at the top and is due to residualmagnetism from a previous space pulse to the illustrated lower coil 48%.The flux lines due to this permanent magnet (plug 424) are shown by thelight dotted lines indicated by the numeral 444. As may be seen, most ofthis flux flows through the mid-plate to complete the circuit, but someof the flux flows up the locks 3-5 9, 388, through the top plug 422,across the air gap 446 and back down through the plunger 4115. Thislatter flux is indicated by the numeral 448. As shown by this diagram,the plunger 416 will be permanently held against the lower plug 424.There is a slight attractive force between the upper tip 418 of theplunger he and the end 453 of the upper plug 42-2, but as there is alarge air gap at the upper end, the attraction is relatively slight andcan be ignored.

When the mark coil 4% at the top of the solenoid is pulsed, as wasexplained earlier, there is a magnetic flux circuit caused to flow asindicated by the heavy dotted lines 45% at the left side of the diagram.Due to the direction of the current pulse in this top coil see, theupper tip 418 of the plunger 4-16 will become a North pole and the lowertip 419 will become a South pole. As the end 431 of the lower plug 424is also a South pole, the two poles will repel one another to releasethe plunger 436 from the magnetic locking effect of bottom magnetizedplug 424. At the same instant that the lower plug 424 releases theplunger, the magnetic field created by How of current in the coil 4%causes the plunger 416 to tend to center itself in the upper coil 4% andit is snapped up into mark position with its upper tip 418 against theconical end 436 of the top plug 42-2.

" The polarity of upper plug 422 is changed by the magnetic flux createdby the current flowing in the top coil see and its conical end 43-? thusbecomes a South pole to attract and magnetically hold the plunger inthis upper position. Due to the fact that the end plugs 422' and 524 areof highly magnetically retentive material, they are slower to respond tochanges in polarity than is the magnetic fiuX circuit and always lagbehind. When the current flows through the windings of the coil 4%, theflux indicated at 45% causes the lower plunger tip 419 to become a Southpole and also causes the end 431 of the bottom plug to become a Northpole. However, the lag mentioned above enables the two parts 419 and 431to be repelled before the end 433 of lower plug 424 has its polaritychanged.

Thus there has been disclosed and described a solenoid plunger which maybe driven one way or the other by alternately energized coils 4456 andi133 and which will always be magnetically locked in its set positionwhen the coils are tie-energized.

Referring now to FlGURE 6, directly beneath the simultaneous solenoidreceiver assembly described above, is a group of five Y-shaped levers452 pivoted on a post (54 and having a slight turning motion one way orthe ill other which is limited by a stop post 456 coacting with thesides of a slot 458 in each Y-lever. The stop post 456 is directly overthe Y-levers pivot post 454 and the slots 453 are slightly wider thanthe diameter of the stop post ass. Clockwise rotation of a Y-lever is aresult of a mark signal and counterclockwise rotation of a Y-lever is aresult of a space signal. These five Y-levers 452 are somewhat similarin appearance to the five Y -levers 248 of the sequential receiver andserve the same purpose. Each Y-lever 452 has three arms, a right-handarm 46%;? and two left-hand arms 462 and 464. Movement of the Y-levers452 is effected through their attachment to associated ones of thesolenoid plunger wires 52i) projecting through the bottom of thesimultaneous receiver housing 86. The front Y-lever has a wire 420aattached to a post 466 at the left of the pivot 454 and is associatedwith the rst element or bit of the Baudot code. The second Y- lever hasthe wire 4261) attached to a post at the right of the pivot and isassociated with the second element of the code. The third Y-lever hasthe wire 42% attached at the left of the pivot 45 iand away from thepivot a distance double that of the first wire. The fourth Y-lever hasthe Wire 42% attached at the right of the pivot and away from the pivota distance double that of the wire 42%. The fifth Y-lever has its wire42% attached to the left of the pivot and directly behind the post 2-66on the first Y-lever. The plungers associated with wires 42%, 4230 and42% move down when their mark solenoids are pulsed and up when theirspace solenoids are pulsed. The plungers associated with wires 52%]; and426d move up when their mark solenoids are pulsed and down when theirspace solenoids are pulsed.

With the described arrangement of the wire connections to the Y-levers,it is necessary that the solenoid plungers 416s and 4160. within thesolenoid receiver housing 3% move twice as far to set the third andfourth Y-levers as to set the first, second and fifth levers due to thegreater distance of the wire attachment from the pivot This differencein movement of the plungers are is adjusted by the screw plugs 422 and424 as was previously explained. The forces necessary to turn theY-levers are about equal regardless of the greater movement of two ofthe plungers due to the fact that the two that have to move the farthestare also farther from the pivot 4-54 so that a greater lever action isavailable for the turning of these latter two levers.

Referring now to FIGURE 5, the operations of the simultaneous receivingand translating mechanism subsequent to positioning of Y-levers 452 willnow be described.

When the five mark or space circuits set up by code plates 2% are pulsedby the pulsing cam 33% on the function shaft 35%, associated ones of themark or space solenoids within the solenoid receiver housing 355 areenergized and magnetically locked to simultaneously move and retain thefive Y-levers 452 to desired clockwise or counterclockwise positions;clockwise for marking impulses and counterclockwise for spacingimpulses. A second transfer lever 468, for transferring settings ofY-levers 452, is fixed on the end of a shaft 4% and, with shaft 47 it,can turn clockwise a slight amount under the biasing force of a spring4'72. This transfer lever 468 is latched in cocked condition against theforce of spring 472. Release of transfer lever 46% is accomplished byenergizing an electromagnet 4'74 which attracts a latching armature 47opivoted at 478 and biased away from the magnet 4 74 by a spring ass. Thearmature 476 has a latching end 482 which engages an end 484 of a latchlever use fixed to the second transfer lever shaft 57d. When the magnetare is energized, the armature 376 pulls up and releases the latch lever4% which in turn permits the transfer lever 46% at the outer end of theshaft 457% to turn under bias of spring 230.

Mounted on the end of an arm 4'73 of the second transfer lever 1-63 is apost 488 which pivotally mounts five T-levers 4%, identical to theT-levers previously de I l 1' scribed for the sequential receiver. Whentransfer lever 46% is released the T-levers 490 are moved forwardagainst the simultaneously positioned Y-levers 452 and one or the otherof the arms 492 or 494 of the T-levers 499 will strike one or the otherof the arms 462 or 464 of the Y-levers 452 to turn the T-levers inclockwise or counterclockwise directions. Clockwise rotation of aT-lever is the result of a space signal and counterclockwise rotation isthe result of a mark signal.

The start or latch electromagnet 474, which releases the second transferlever 468 as described above, is controlled through contacts 496 (when acontrol switch 551, later described, is in position 3) by the cam 380 onthe function shaft 35%. Contacts 4%, associated with earn 380, areclosed at approximately the same time as the aforementioned contacts 382are closed to pulse the solenoids in the simultaneous receiver. Contacts496 are in series with the latch electromagnet 4'74, therefore, at thesame time the solenoids within the simultaneous receiver are energizedto effect the setting of the simultaneous Y- levers 452, theelectromagnet 474 is energized to release the transfer lever 468.Electromagnet 474 is made to respond more slowly than the solenoids sothe Y-levers will always be completely set before the T-levers 4% strikethem. This delay of the magnet 474 can be accomplished in any of anumberof known ways, such as placing two switch actuating portions of cam 380in slightly staggered relationship or using an electrical delay circuit,but it is to be understood that the Y-levers 452 must be completely setbefore the T-levers 490 are moved into engagement therewith.

Each T-lever 490 has a tip 498 which engages a notch 5% in an arm 504 ofa code device, as for example, a permutation ring 500 shown in FIGURES1, 5 and 9. There are five of these rings 50%) and when they are rotatedto clockwise and counterclockwise positions by the action of T-levers490 turning in counterclockwise and clockwise directions, one of aplurality (32in this embodiment) of stop bars 506 will be sprung into achannel of lined-up notches 508 in the five rings. Once one of the 32stop bars 596 has been selected by dropping into the aligned notches508, the T-levers 496 may be disengaged from the Y-levers 452 to freethe latter for a new selection. The restoring of the T-levers 499 to aposition out of engagement with the Y-levers is accomplished in a mannersimilar to that used in restoring of the T-levers 286 of the sequentialselector; A cam 510 at the end of a second function shaft 512 cooperateswith a roller 514 at the end of an arm on the transfer lever 468. Whenthe transfer lever 463 is released, its pivotal movement swings roller514 against the flat side of'cam 510 and subsequent rota tion of cam 510causes the transfer lever 468 to be turned counterclockwise a distancefar enough to permit the latch lever 486, at the opposite end of thetransfer lever shaft 47%), to become latched behind the latch end 482 ofarmature 476.

' Rotation of the second function'shaft 512 to effect the abovedescribed restoration of the transfer lever is accomplished as follows:At the right-hand end of the shaft 512, FIGURE 5, 'a rotatably mountedspur gear 516 is in mesh with and constantly rotated by an idler gear518 which in turn is constantly rotated by the train of gears 354 and356. On the left face of the rotatably mounted gear 516 isa toothedclutch driving element 520 normally out of engagement with a drivenclutch element 522. The driven clutch element 522, non-rotatably keyedto and axially shiftable on function shaft 486 is released by movementof the armature latch 482,

on the reperforator.

"l2 dog 524 on the sliding clutch element 522 which will axially shiftunder bias of spring 528 and become engaged with the driving clutchelement 520 to cause shaft 'result of rotation of the second functionshaft 512 during its one-half revolution but the only purely mechanicalone to be dealt with here is the positioning of a type selecting shaft530. A large gear '532'is rotatably mounted on the shaft 512 andis'caused to turn with the shaft by spring pressed friction plates 534,only one of which can bev seen in FIGURE 5. The friction plates. 7

are keyed to the shaft 512 and always turn-with it. In mesh with thegear 532 is a smaller gear 536 fixed to the type selecting shaft 530. Atthe left end of the type selecting shaft 530 is a stop arm 538,constructed to rotate inside of the stop bars 506 and to be arrested byany bar which is selected by dropping into aligned notches of the coderings 500.

It follows then that when the second function shaft 512 starts torotate, the type selecting shaft 530 will also start torotate and thelatter shaft 530 will continue to rotate until stop arm 538 contacts aselected stop bar 506. The' s haft 530 will then stop due to theslippage 0f the gear 532 on the faces of the friction clutch 534. Thetype selecting shaft 530 will thus have been rotated to an angularposition which corresponds to a type character represented by the codereceived at the simultaneous receiver.

7 One other mechanical electrical operation performed by the secondfunction shaft 512 is an important part of this invention. Attheright-hand end of the function shaft 512 is a cam 540 whichcooperates with two normally closed pairs of contacts 542 and 544,opening them at certain timed intervals, and with a pair of normallyopen contacts 546, closing them at timed intervals.

The purpose of each of these pairs' of contacts will be disclosed in thedescription of the overall electric circuit to be hereinafter completelydescribed.

. r SWITCHING CIRCUIT Although not part of the present invention, aswitching circuit for interconnecting a system transmitting componentwith the receiving elements of this invention is shown inFIGURE 10 andwill aid in showing the manner in which the present invention is used.At the righthand side of the diagram is a three position switch 551having four independent banks 552a, 552b, 5520 and 552d. The threedifferent positions of the switch, as

illustrated, allow the following arrangements; It is obvious thatadditional combinations ing positions to the switch.

Position 1 Keyboard (simultaneous sending) to reperforator(simultaneous) receiver; This is the free keyboard condition of thesystem described in parent application Serial No. 628,110. The operatormay manipulate the keyboard at any cadence or rhythm to print and punchtape Position 2 Keyboard (simultaneous sending) to reperforator(simultaneous) receiverKeyboard (sequential sending) to outgoingline;The operator may work the keyboard to send a message by sequentialsending to an outgoing line (which may be a monitoring page printer) andat the same time have the same message punched and printed on tapefbythe reperforator. The speed at which the maybe had by add- 13 keyboardmay be operated is limited by the speed of the machines on the outgoingline.

Position 3 Keyboard (sequential sending) to outgoing line-Reperforator(sequential receiving) from incoming line: The operator may send amessage from the keyboard to an outgoing line by sequential signals andat the same time an incoming message may be printed and punched on tapeby the reperforator.

Setting switch 551 in N0. 1 position enables the operator to manipulatethe keyboard to send simultaneous signals to the reperforator which willprint and punch tape. Referring now to FIGURE 10, sequential signalswill not be sent because the sequential transmitter is prevented fromoperating by a lock solenoid 224. The reperforator will not respond tosignals from the incoming line because the common circuit through switchplate contact strip 338 for the solenoids 4436, 26 8, etc, is open atswitch contacts 552s (3).

With the switch 551 set in No. 1 position, current from battery 55% willenergize the coils of lock solenoid 224 at the keyboard through theswitch contacts 552a (l) and thence back to the negative side of thebattery. The keyboard transmitter shaft 58 is thus prevented fromrotating so sequential signals will not be sent. Upon the pressing of akey lever 22, the keyboard code bars 29 will be set in left and righthand positions and the keyboard universal bar 86 moves to the right torelease the keyboard transmitter stop lever 92 and to close the contacts220 and 222. The contacts 222, when closed, will put battery current onthe simultaneous receiving circuit as follows: from the positive side ofbattery 55% through the closed contacts 542 to the common side of t esolenoid coils 45 6 and 498, through the coils and to a space contact178 and mar contact 376 of the simultaneous switch at the keyboard;through the sliding switch arm 174 to the switch contact 5521: (1)through the closed contacts 222 to the negative side of battery 55%.Hence, certain mar and space solenoids in the simultaneous receiver willbe energized and the Y-levers 452 will be set accordingly.

The closing of contacts 22%), which also occurs when the keyboardtransmitter stop lever 92- drops, will set up the circuit to release thereperforator transfer lever 4-58 and permit rotation of thereperforators second function shaft 512. This circuit may be traced asfollows: from battery 55% through closed contacts 54- throughreperforator latch magnet 474 to switch contact 552a (1) through thecontacts 22%, to negative side of battery 55% Thus, the latch magnet 474will be energized to pull on the armature latch 476 and release thesecond function shaft 512. As soon as the function shaft 512 starts torotate, the cam 54% presents its lobe to the contacts 544 and 542 toopen their circuits. Thus, the current is taken off the simultaneousreceiver solenoids and off the start magnet 4'74 of function shaft 512.

The function shaft 512 continues to rotate to complete the selecting,printing and perforating of the desired character corresponding to thedepressed keyboard lever 22. Shortly before the function shaft 53.2 isarrested by the latch lever 476, the lobe of the cam closes the contacts546 and a current pulse is delivered from battery 55!) through theswitch contact 552d (1), to the coils of a keyboard transmitterrestoring solenoid res and to negative battery. Thus, the restoringsolenoid in the keyboard transmitter is pulsed to pull stop lever 92 upinto latching position and the contacts 222 and 220 are again opened.

Due to the fact that the receiving reperforator function shaft 512cycles at a considerably higher speed than an operator can manipulatethe keyboard, the transmitter cam stop lever 92 is always restored andin readiness to be released by the depressing of another key lever. Thekeyboard is thus practically unlimited in its speed of manipulation whenthe switch 551 is in this position No. 1.

Setting switch 551 in N0. 2 position will permit the operator to workthe keyboard to concurrently send sequential signals to the outgoingline and simultaneous signals to the reperforator. The sequentialsignalling transmitter shaft 58 is permitted to rotate because the locksolenoid 22 4 is not energized inasmuch as contacts 5520 (2) are open.

When a key lever 22 is depressed, the code bars 26 take their left andright hand positions and the universal bar 3% releases the cam stoplever $2 to permit the keyboard transmitter shaft 58 to turn and closecontacts 229 and 222. The closing of the contacts 222 will put currenton the simultaneous receiving circuit just as before but in this secondposition the circuit i through switch contacts 552b (2). The startmagnet 474 for the reperforator second function shaft 5'12 will bepulsed by current from battery 55'!) through contacts 544, through thecoil of electromagnet 474 to the switch contacts 552a (2), through thecontacts 14-6 closed by transmitter shaft cam 134 and to negative ofbattery. The simultaneous receiver then finishes it cycle just asbefore. i

As this No. 2 switch position also sends the keyboard initiated messageto the telegraph line, the sequential transmitter will cycle, havingbeen released as stated above, to transmit the code group. Shortly afterthe sequential transmitter shaft 58 has started to rotate, restoringsolenoid 162 will be energized from battery 55% through contacts 133,also closed by the transmitter shaft cam 134, through the solenoid coilllilZ to negative battery. The cam stop lever 92 will thus be lifted toits stop position and the stop lever actuated contacts 222 will beopened. The transmitter shaft 58 completes its cycle and stops, awaitinganother key lever to be depressed.

in the above described operation, the keyboard manipulating speed isunder the control of the sequential transmitter speed due to the lockingof the code bars by the keyboard sensing levers locking bail 15b. Thisis obviously necessary when transmitting a message to a telegraph linewhich has a definite predetermined transmitting cadence.

By setting the switch 55. in N0. 3 position the keyboard can sendsequential signals to an outgoing line and the reperforator can receivesequential signals from an incoming line. The simultaneous sendingcircuit is ineffective because the circuit through common liue 214 isopen at contacts 552i: (3). All other electrical circuits between thekeyboard and the reperforator are open when the switch 551 is in No. 3position. In this condition the keyboard transmits to the outgoing linein the same manner as in position 2.

The reperforator is in condition to receive sequential signals over theincoming line. The reception of a start signal will cause the selectormagnet 2 to release the receiver shaft 258 which will rotate to positionthe sliding switches 308. The sliding switches 3&8 are set in mark andspace positions on the switch plate $24 by the sequential receiving andselecting mechanism and are locked there. The cam 38% then closescontacts 332 which completes a circuit to connect battery 559 to thesimultaneous receiving solenoids through the contacts 542 to the commonlead to the solenoids, through the coils 4% or 46 8, to the mark segment342 and to the space segment 344 of the code bar switching plate 3%. Forthe mark position shown, the circuit proceeds through the contact see tothe common segment 333, through the contacts 382, to switch contacts552s (3), to negative battery. The simultaneous receiver 386 is thusenergized to set the Y-levers .52.

Cam 384) also closes contacts 4% to place the battery 550 in circuitwith the start magnet 474, which circuit is through contacts 544,through the coil of start magnet 474, to switch contacts 552a (3),through contacts 4% and to negative battery. Thus, the simultaneousreceiver shaft 512 is released, the transfer of the Y-lever settings tothe code rings 5% takes place and a printing cycle is completed torecord the character identified with the incoming signal.

In the foregoing description and drawings, new printing telegraphequipment has been disclosed which will enable greater vesrsatilitybetween keyboard transmitter units and receiver mechanisms than hasheretofore been obtained. The receiving mechanism can receive code signal combinations in either sequential or simultaneous form and includesa sequential receiver and translator and a simultaneous receiver andtranslator, the two receivers and translators working in series whenreceiving sequential signals and only the simultaneous receiver andtranslator being operative when simultaneous code signal combinationsare received. Many combinations of transmitting and receiving equipmentcan be realized with this new equipment in addition to use of standardpage printers for monitoring keyboard transmission or receiving incomingmessages and perforated tape transmitters for transmission of storedmessages. trate various arrangements of the sequential-simultaneouskeyboard transmitter used with a reperforator embodying the sequentialand simultaneous receiver and a standard monitor which may be used withthe keyboard. Although the keyboard transmitter operational speed isalways limited by the standard line operational cadence, e.g., 60 wordsper minute, whenever sequential transmission is being accomplished, onearrangement, which uses only simultaneous transmission from a keyboardto the simultaneous portion of the reperforator, bypasses the cadencecontrol required in sequential transmission, resulting in anessentially'free keyboard for unlimited speed within the range of ahuman operator. 7 The invention may be embodied in other specific formswithout departing from the spirit or essential characteristics thereof.The present embodiment is therefore to be considered in'all respects asillustrative and not restrictive, the scope of the invention beingindicated by the appended claims rather than by the foregoingdescription, and all changes which come within the meaning and range ofequivalency of the claims are therefore intended to be embraced therein.
